UCC28180: need a power solution 240W ,AC-DC flyback

Hello Alex,

The Onsemi reference design uses the NCP1680, which is a pure analog controller IC. Currently, TI does not offer a pure analog Totem Pole PFC solution. Our existing designs include using the C2000 microcontrollers, or the UCD3138x controllers. The C2000 are DSP-based microcontrollers. The UCD3138x controllers also require firmware but include integrated hardware loops and a GUI for easy configuration.
